Thunk from the back?
87 Wagoneer limited with the inline six gives a random thunk from the back near the hatch when accelerating at a fast pace and or suddenly letting off the throttle

Easy check there
I would also check ujoints and trans mount
Go ahead and check motor mounts as well while your at it
I had a bad motor mount and for some reason when it made a noise it sounded like it was in the cargo area.
Good luck

I think I should also mention that there is on occasional vibration on the passenger side front of the jeep when i go above 55 mph but the tires are brand new and from what i see the suspension parts are in relatively good shape. As far as the mounts I am gonna take her to a shop today and put her on a lift and post some pics.

Already done all the usual things regarding this. Replaced trans and engine mounts, tht decreased the clunk for 80%, it came back, tightended the transmount bolts, came back again, was my crossmember coming loose on one side, greased the slipyoke, checked the U-joint and leafsrping U-bolts,....and now its increasing again....might regrease the slip againm although that didnt change anything actually.

I used lithium NLG2 grease I think, just a general automotive high pressure etc grease. But I've come across some that use antiseize...might be an idea for next time. There is not a maintenance interval, for some greasing fixed it, for me it did not...

I found out what the vibration in the front was.. passenger side CV axle is on its way out and the tail pipe is knocking in the back so.. another thing to add to the list
